Developing of Net Virtual Reality Material Test Platform

The developing method of net virtual reality material test platform(NVRMTP) is discussed from the view of software developing based on the developing of net virtual reality metallographic test platform(NVRGTP).The design of NVRMTP should follow the certain principle as following: system positioningdemand analysispreliminary designdetailed design.The developing skill of virtual reality system based on VRML is illustrated,and may be important to the development of other system.
